Datania's suit gives her a svelter shape.

7 of 8
Datania Gregg, 30
Before: All that bare midriff does nothing to give Datania's straight-lined body a more nipped-in look. Besides, the suit is too small: The bottoms cut into her hips, and she spills out of the top.

After: Similar pattern (black backgrounds are more slenderizing than paler prints), svelter shape: This maillot (Liz Claiborne, $93) has seaming to mold Datania's torso, plus shirring and a shelf bra for a bust-minimizing effect.
